ABSTRACT:
A lithium metal oxide positive electrode for a non-aqueous lithium cell is disclosed. The cell is prepared in its initial discharged state and has a general formula xLiMO2.(1−x)Li2M′O3in which 0<x<1, and where M is one or more ion with an average trivalent oxidation state and with at least one ion being Mn or Ni, and where M′ is one or more ion with an average tetravalent oxidation state. Complete cells or batteries are disclosed with anode, cathode and electrolyte as are batteries of several cells connected in parallel or series or both.
